Who is responsible for establishing hold lines/signs at an airport?

The airport manager holds the responsibility for establishing hold lines and signs at an airport. This role involves overseeing the overall operation and safety of the airport, which includes the proper placement and maintenance of various signs and markings essential for the safe movement of aircraft on the ground. The airport manager must ensure that hold lines comply with regulatory standards and support safe operations by guiding pilots and ground vehicles at the airport.

While the other roles may have important functions within the airport operations, they do not typically involve the specific responsibility of designating or maintaining signage and markings. Air traffic controllers, ground control specialists, and those involved in flight operations can provide input or support, but the authority and accountability for that aspect rest with the airport manager.
